Full-term Pregnancy Induces a Specific Genomic Signature in the Human Breast

Abstract excerpt

Breast cancer risk has traditionally been linked to nulliparity or late first full-term pregnancy, whereas young age at first childbirth, multiparity, and breast-feeding are associated with a reduced risk. Early pregnancy confers protection by inducing breast differentiation, which imprints a specific and permanent genomic signature in experimental rodent models. For testing whether the same phenomenon was...
